The pot being very thin (8/10), the resonance is at the top, the high revs too, it is really necessary to put this exhaust on engines over-boosted and well adjusted.
Technically, this exhaust is realized in the following way :
- Steel sheet thickness 8 / 10th mm, laser cut
- Unit rolling of each cone
- Unitary welding of the seam of each cone by TIG welding
- Setting up each cone and pointing by TIG welding
- Welding of the pot by oxy-acethylene
- Each weld is tapped, so as not to have a weld bead inside the pot
